What Is Adjusted Gross Income (AGI) and Why Does It Matter?

When you file your taxes, you’ll hear a lot about Adjusted Gross Income (AGI)—but what exactly is it, and why is it so important? Let’s break it down!

🔎 What Is AGI?

Adjusted Gross Income (AGI) is your total gross income (everything you earn) minus certain deductions or adjustments allowed by the IRS. It’s a key figure because it determines your taxable income, which affects how much you owe in taxes.

💰 What’s Included in AGI?

Your AGI starts with your gross income, which includes:

  • Wages, salaries, and tips

  • Self-employment income

  • Investment income (like dividends, interest, and capital gains)

  • Rental income

  • Retirement income

  • Unemployment benefits

Then, you subtract adjustments such as:

  • Student loan interest

  • Retirement contributions (like IRA or 401(k) contributions)

  • Health savings account (HSA) contributions

  • Self-employment expenses

These adjustments reduce your gross income to calculate your AGI.

📊 Why Does AGI Matter?

Your AGI is important because:

  1. Tax Brackets: AGI helps determine which tax bracket you fall into, affecting your overall tax rate.

  2. Eligibility for Credits & Deductions: Many tax credits and deductions are based on your AGI. For example, the Child Tax Credit and Education Credits phase out at higher AGIs.

  3. Determines Taxable Income: Once you subtract your AGI from any other deductions (like the standard or itemized deductions), you get your taxable income—the amount you’re actually taxed on.

📉 How to Lower Your AGI

To lower your AGI (and potentially reduce your taxes), you can:

  • Contribute more to tax-deferred accounts like 401(k)s or IRAs

  • Take advantage of HSA contributions

  • Deduct student loan interest

  • If you’re self-employed, deduct eligible business expenses

✅ Pro Tip: Keep track of your income and expenses throughout the year, and consider working with a tax pro to optimize your AGI and minimize your tax liability.
